Place value within 10 - Comparing activity - Presentation

In Lesson 15, focused on place value within 10, students are introduced to the concept of comparing numbers using inequality symbols. The lesson's objective is to help students understand and prove inequality statements with practical equipment. At the beginning of the lesson, students are encouraged to discuss the meaning of 'prove' and how it applies to mathematical statements. The lesson presentation guides them through the process of identifying the symbols for 'greater than', 'less than', and 'equal to', and prompts them to discuss their meaning and application in comparing numbers.

During the activities, students are tasked with drawing these comparison symbols around cubes to visually represent the relationships between different quantities. They are challenged to translate these visual representations into written statements, further reinforcing their understanding of the symbols and their use in expressing numerical relationships. The lesson progresses to an independent work section where students select cards and use hands-on equipment to validate the truth of given statements, exploring the possibility of multiple answers and different ways to represent the same comparison. This engaging approach to learning place value encourages critical thinking and a deeper grasp of mathematical concepts related to comparing quantities.
